Environmental data associated with the first route is received from a second group of one or more sensors. Environmental data associated with a second route is received from the second group of one or more sensors. It is determined whether to modify the first route into the second route based on the background data, the physiometric data, and the environmental data associated with the first route and the environmental data associated with the second route, and the determination occurs while the group of one or more users is traversing the first route.

BACKGROUND OF THE INVENTION

The present invention relates generally to autonomous vehicles, and more particularly to dynamic navigation of autonomous vehicles.

Recent advances have focused on making vehicles operationally-autonomous or at least semi-autonomous. Autonomous vehicles, such as unmanned aerial vehicles (UAVs), can be remote controlled (i.e., flown by a pilot at a ground control station), or can fly autonomously based on pre-programmed flight plans or complex dynamic automation systems. Autonomous vehicles are finding uses in various civil (e.g., commercial and recreational) applications, such as photography and surveillance.

In an embodiment of the present invention, background data of a first user in a group of one or more users is received. Physiometric data of the first user while the group of one or more users is traversing a first route is received from a first group of one or more sensors. Environmental data associated with the first route is received from a second group of one or more sensors. Environmental data associated with a second route is received from the second group of one or more sensors. It is determined whether to modify the first route into the second route based on the background data, the physiometric data, and the environmental data associated with the first route and the environmental data associated with the second route, and the determination occurs while the group of one or more users is traversing the first route.

DETAILED DESCRIPTION

Embodiments of the present invention recognize that an autonomous machine can be a safer, cheaper, and more efficient alternative to a person doing the same job. For example, a machine can receive and process data from several different sources simultaneously while also carrying out other tasks. Embodiments of the present invention further recognize that current methods of providing navigation to an unmanned vehicle do not account for the cognitive or somatic information received from users of the unmanned vehicle during the navigation. Embodiments of the present invention provide for an autonomous guidance system that determines a route based on real-time cognitive and somatic information.

The present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram of a computing environment, generally designated 100, in accordance with an embodiment of the present invention. FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Those skilled in the art may make many modifications to the depicted environment without departing from the scope of the invention as recited by the claims.

In an embodiment, distributed data processing environment 100 includes remote controlled vehicle 110, sensor device 120, and server device 130. Remote controlled vehicle 110, sensor device 120, and server device 130 are interconnected through network 102. In an embodiment, distributed data processing environment 100 may additionally include any other computing device connected to network 102.

In an embodiment, network 102 may be a near field communication network (NFC), a broadcast communication network (e.g., GPS, terrestrial network), a local area network (LAN), a telecommunications network, a wide area network (WAN) such as the Internet, a low power WAN or a long range WAN (e.g., LoRaWAN), or a combination of thereof. Network 102 may include wired, wireless, or fiber optic connections. In an embodiment, network 102 may generally be any combination of connections and protocols that support communications between remote controlled vehicle 110, sensor device 120, server device 130, and any other computing device connected to network 102, in accordance with embodiments of the present invention.

In an embodiment, remote controlled vehicle 110 (RCV 110) may generally be any vehicle that is operable without a human pilot aboard the vehicle. As an example embodiment, RCV 110 may be an unmanned aerial vehicle (UAV). In an embodiment, RCV 110 may be controlled with varying degrees of autonomy. For example, RCV 110 may be fully autonomous such that RCV 110 is fully controlled by means (e.g., computing devices) onboard RCV 110. As another example, RCV 110 may be partially controlled by a remote (i.e., not onboard) human user and partially controlled by means onboard RCV 110. As another example, RCV 110 may be fully controlled by a remote human user. In an embodiment, RCV 110 may act as a tour guide by guiding tour participants along a route. For example, RCV 110 may guide a group of participants along a route through a national park. In an embodiment, RCV 110 is capable of executing computer readable program instructions. In an embodiment, remote controlled vehicle 110 may include components depicted and described with respect to FIG. 3.

In an embodiment, sensor device 120 may be one or more sensor devices that identify and collect environmental data as well as physiometric data of persons associated with the one or more sensors. In an embodiment, during route navigation by RCV 110 (e.g., during a tour guided by RCV 110), sensor device 120 continuously identifies and collects the environmental data and the physiometric data of participants traversing a route navigated by RCV 110. In an embodiment, environmental data includes weather conditions (e.g., temperature, humidity, wind speed, dangers or obstacles) and crowd data (e.g., identifying the number of non-participant people on the current route). Environmental data includes data relating to a route currently being navigated by RCV 110 as well as data relating to other areas, or potential new routes. In an embodiment, physiometric data may include measurable biological and neurological characteristics including blood pressure, heart rate, heart rate variability (HRV), body temperature, respiration levels, glucose levels, gestures, facial expressions, voice recognition, and brain activity (e.g., alpha waves).

In an embodiment, sensor device 120 may be a wearable device that is worn by a person, and sensor device 120 collects physiometric data associated with that person. For example, sensor device 120 may be worn by each participant of a tour guided by RCV 110, and during the tour, sensor device 120 continuously detects, and sends to optimization engine 132, the physiometric data associated with each tour participant. In an alternative embodiment, sensor device 120 may be located on RCV 110 instead of, or in addition to, being a wearable device worn by each participant. In an embodiment, sensor device 120 communicates the environmental data and the physiometric data to optimization engine 132 through network 102, and the data is stored in data repository 134.

In an embodiment, server device 130 may generally be any electronic device or combination of electronic devices capable of executing computer readable program instructions. In example embodiments, server device 130 may be a workstation, personal computer, personal digital assistant, or mobile phone. In an embodiment, server device 130 may be a computer system utilizing clustered computers and components (e.g., database server devices or application server devices) that act as a single pool of seamless resources when accessed by elements of distributed data processing environment 100, such as in a cloud computing environment. In an embodiment, server device 130 may be computer 300 and may include components depicted and described with respect to FIG. 3.

In an embodiment, server device 130 includes optimization engine 132. In an alternative embodiment, optimization engine 132 may be located on RCV 110. In yet another alternative embodiment, optimization engine 132 may be located on another computing device (not shown) connected to network 102. In an embodiment, optimization engine 132 may generally be a computer program, application, subprogram of a larger program, or combination thereof that optimizes a route to be traveled by RCV 110 based on cognitive, affective, and somatic states of associated persons, or participants. In an embodiment, a route is a specified course of travel between locations. As an example, RCV 110 may act as a tour guide by leading, or guiding, a tour group along a route, and the participants in the tour group are associated with RCV 110. Optimization engine 132, in that case, would optimize a tour route for RCV 110 based on the cognitive, affective, and somatic states of the tour participants, and RCV 110 would travel along the optimized route, guiding the participants.

In an embodiment, optimization engine 132 communicates with RCV 110, sensor device 120, and data repository 134 for optimizing a route to be traveled by RCV 110. In an embodiment, optimization engine 132 optimizes the route based on background data corresponding to each participant, or person associated with optimization engine 132, on environmental data, and on physiometric data of each participant.

In an embodiment, background data includes age, gender, preferred language, profession (e.g., physician), physical disabilities (e.g., requires a wheelchair), special fears (e.g., claustrophobic), special interests (e.g., history), special skills (e.g., certified in cardiopulmonary resuscitation (CPR)), previous tour experiences and evaluations, or tour objectives. In an embodiment, a tour objective includes one or more goals to be accomplished during the tour such as goals related to learning, physical fitness, time, or mental stress and relaxation. For example, a tour objective of a participant may be to achieve a high level of relaxation without regard to learning or physical fitness. As another example, a tour objective may be to achieve a combination of a high level of physical fitness and some level of learning, and to do so for no longer than two hours.

In an embodiment, optimization engine 132 receives the background data through a user interface of optimization engine 132. In an alternative embodiment, optimization engine 132 receives the background data from one or more computing devices connected to network 102. For example, each participant may indicate the background data to optimization engine 132 through a personal computer (not shown) connected to network 102.

A user interface is the information, such as graphic, text, and sound, a program presents to a user and the control sequences the user employs to control the program. There are many types of user interfaces. For example, the user interface may be a graphical user interface (GUI). A GUI is a type of user interface that allows users to interact with electronic devices, such as a keyboard and mouse, through graphical icons and visual indicators, such as secondary notations, as opposed to text-based interfaces, typed command labels, or text navigation. GUIs were introduced for computers in response to the perceived steep learning curve of command-line interfaces, which required commands to be typed on the keyboard. The actions in GUIs may be performed by a user through direct manipulation of the graphical elements.

In an embodiment, server device 130 includes data repository 134. In an alternative embodiment, data repository 134 may be located on RCV 110. In yet another alternative embodiment, data repository 134 may be located on another computing device (not shown) connected to network 102. In an embodiment, data repository 134 may generally be a storage location for the physiometric data and the participant background information.

In an embodiment, data repository 134 contains the physiometric data collected by sensor device 120 during route navigation of RCV 110 and the participant background data collected prior to route navigation of RCV 110. In an embodiment, physiometric data stored in data repository 134 includes measurable physiological characteristics including blood pressure, heart rate, HRV, body temperature, respiration levels, glucose levels, gestures, facial expressions, voice recognition, or brain activity (e.g., alpha waves). In an embodiment, background information stored in data repository 134 includes age, gender, preferred language, profession (e.g., physician), physical disabilities (e.g., requires a wheelchair), special fears (e.g., claustrophobic), special interests (e.g., history), special skills (e.g., certified in CPR), previous tour experiences and evaluations, and tour objectives. In an embodiment, the physiometric data and the background data are associated are stored and associated with each participant of the tour. Optimization engine 132 may access data repository 134 to add to, remove, edit, or otherwise utilize the data physiometric data and the participant background information.

In an embodiment, data repository 134 may be implemented using any non-volatile storage media known in the art. For example, data repository 134 may be implemented with a tape library, optical library, one or more independent hard disk drives or flash drives, or multiple hard disk drives or flash drives in a redundant array of independent disks (RAID). Data repository 134 may be implemented using any suitable storage architecture known in the art. For example, data repository 134 may be implemented with a relational database or an object-oriented database.

FIG. 2 is a flowchart of workflow 200 illustrating operational steps for optimizing a route based on the cognitive, affective, and somatic states of one or more persons. In the illustrated embodiment, the steps of workflow 200 are performed by optimization engine 132. In an alternative embodiment, steps of workflow may be performed by any other computer program while working with optimization engine 132. In an embodiment, optimization engine 132 begins performing the steps of workflow 200 in response to receiving an indication by a user to optimize a route based on the cognitive, affective, and somatic states of one or more persons. In an embodiment, a user may provide such an indication through the user interface of optimization engine 132.

Optimization engine 132 receives background data of each participant (step 205). In other words, in an embodiment, optimization engine 132 receives background data of each participant of a tour to be guided by RCV 110. In an embodiment, background data of a participant may include age, gender, preferred and understood languages, profession (e.g., physician), physical disabilities (e.g., requires a wheelchair), special fears (e.g., claustrophobic), special interests (e.g., history), special skills (e.g., certified in CPR), previous tour experiences and evaluations, and tour objectives. In an embodiment, tour objectives of a participant may include goals to be accomplished during a tour such as goals related to learning, physical fitness, tour duration, or mental stress and relaxation. For example, a tour objective of a participant may be to achieve a high level of relaxation without regard to achieving learning or physical fitness goals. As another example, tour objectives of a participant may be a high level of physical fitness, a medium level of learning, and a tour duration of no longer than two hours.

In an embodiment, optimization engine 132 receives the background data from one or more computing devices connected to network 102. For example, prior to a tour guided by RCV 110, each participant of the tour may indicate the background data to optimization engine 132 through a personal computer or mobile device connected to network 102. In an alternative embodiment, optimization engine 132 receives the background data through the user interface of optimization engine 132. In an embodiment, the background data is stored in data repository 134.

Optimization engine 132 determines a route based on the background data (step 210). In other words, optimization engine 132 determines a route of a tour to be guided by RCV 110 based on the background data of each participant. For example, where a majority of the tour participants indicated a tour objective of a high level of physical fitness and a fear of heights, optimization engine 132 may determine a route for RCV 110 that includes several extreme changes in elevation (e.g., through a mountainous area) and is not near any cliff faces.

In an embodiment, a route for RCV 110 has been previously determined, and optimization engine 132 modifies the existing route such that the route accommodates the background data of each participant. For example, where optimization engine 132 determines that the background data of participants of a current tour is similar to the background data of participants of a previous tour at the same location, optimization engine 132 may determine the same route for RCV 110 to utilize for the current tour. Where a majority of participants of the current tour indicated a tour objective of a one-hour tour duration, and the previous tour had a duration of thirty minutes, optimization may modify the existing route to be twice the original distance.

Optimization engine 132 determines physiometric data of each participant (step 215). In other words, during a tour, optimization engine 132 continuously receives physiometric data of each participant from sensor device 120 while the participant is traversing the route guided by RCV 110. In an embodiment, physiometric data includes measurable biometric and neurological characteristics including blood pressure, heart rate, HRV, body temperature, respiration levels, glucose levels, gestures, facial expressions, voice recognition (e.g., determining the subject matter of questions asked by participants while traversing the route), and brain activity (e.g., alpha waves).

In an embodiment, sensor device 120 may be a wearable device that is worn by each participant of a tour guided by RCV 110, and sensor device 120 collects physiometric data associated with that person. In an alternative embodiment, sensor device 120 may be located on RCV 110 instead of, or in addition to, being a wearable device worn by each participant. For example, sensor device 120 may include a camera to detect facial expressions, and optimization engine 132 may associate various facial expressions or micro expressions with moods such as happiness, fear, or anger.

Optimization engine 132 determines environmental data (step 220). In other words, during a tour, optimization engine 132 continuously receives environmental data from sensor device 120. In an embodiment, environmental data includes weather conditions (e.g., temperature, humidity, wind speed, dangers or obstacles) and crowd data (e.g., identifying the number of non-participant people on the current route). In an embodiment, a danger or obstacle may include, for example, a forest fire, a rock slide, a tornado, a hunter, and a dangerous wild animal (e.g., bear). In an embodiment, optimization engine 132 additionally determines environmental data from websites or social media platforms. For example, optimization engine 132 may determine that there is a forest fire along or near the route based on a recent news article received from a website, or based on user submissions or user status updates on social media platforms.

Optimization engine 132 optimizes the route based on the background data, the physiometric data, and the environmental data (step 225). In other words, during the tour, optimization engine 132 modifies the route being navigated by RCV 110 based on the background data collected prior to the tour, the physiometric data continuously received during the tour, or the environmental data continuously received during the tour, or a combination of the foregoing data categories. In an embodiment, the route comprises one or more points of interest to which RCV 110 navigates, and optimization engine 132 modifies the route by adding or removing one or more points of interest from the route.

In an embodiment, optimization engine 132 continuously compares the background information, including the tour objectives, with the current physiometric data determined for each participant to determine whether the background information is satisfied by the route. In an embodiment, where optimization engine 132 determines that the current physiometric data does not satisfy the background information, optimization engine 132 modifies the route to be navigated by RCV 110 into a new route based on environmental data.

As an example, where a majority of participants indicated a tour objective of a high level of physical fitness, and no participants indicated physical disabilities, and the majority of participants have an average or below average heart rate and respiration levels, optimization engine 132 may optimize the route by increasing the speed of travel of RCV 110, decreasing the amount of stops to be taken by RCV 110 during the route, and navigating RCV 110 through more inclined terrain and less flat terrain. As another example, where a majority of participants indicated a tour objective of stress relief, and optimization engine 132 determines that a majority of participants have blood pressure levels that have increased since the start of the tour, optimization engine 132 may optimize the route by utilizing crowd data received from sensor 120 and navigating RCV 110 through the least crowded pathways and the shortest route to the end of the tour. As another example, where a majority of participants indicated a special interest of history and optimization engine 132 determines that, based on facial expressions or micro expressions of participants detected by sensor 120, a majority of participants are currently unhappy or bored, optimization engine 132 may optimize the route by navigating RCV 110 to a nearby historical national monument.

In an embodiment, optimization engine 132 continuously analyzes the environmental data to determine dangers or obstacles along the route. Where optimization engine 132 determines a danger or obstacle along the route, optimization engine 132 modifies the route to be navigated by RCV 110 into a new route based on the environmental data that avoids the danger or obstacle. For example, where optimization engine 132 determines, based on data received from sensor 120, websites, or social media platforms, that a forest fire is nearby to the west of the route, optimization engine 132 modifies the route into a new route that is farther to the east of the forest fire.
